Different ways of looking at P/E Ratio vs EPS
"You could not have two stocks both at $40, both with P/E 2, but one an EPS of $5 and the other $10.  EPS = Earnings Per Share P/E = Price per share/Earnings Per Share So, in your example, the stock with EPS of $5 has a P/E of 8, and the stock with an EPS of $10 has a P/E of 4.  So no, it's not valid way of looking at things, because your understanding of EPS and P/E is incorrect. Update: Ok, with that fixed, I think I understand your question better. This isn't a valid way of looking at P/E. You nailed one problem yourself at the end of the post: The tricky part is that you have to assume certain values remain   constant, I suppose But besides that, it still doesn't work. It seems to make sense in the context of investor psychology: if a stock is ""supposed to"" trade at a low P/E, like a utility, that it would stay at that low P/E, and thus a $1 worth of EPS increase would result in lower $$ price increase than a stock that was ""supposed to"" have a high P/E. And that would be true. But let's game it out: Scenario Say you have two stocks, ABC and XYZ. Both have $5 EPS. ABC is a utility, so it has a low P/E of 5, and thus trades at $25/share. XYZ is a high flying tech company, so it has a P/E of 10, thus trading at $50/share. If both companies increase their EPS by $1, to $6, and the P/Es remain the same, that means company ABC rises to $30, and company XYZ rises to $60. Hey! One went up $5, and the other $10, twice as much! That means XYZ was the better investment, right? Nope. You see, shares are not tokens, and you don't get an identical, arbitrary number of them. You make an investment, and that's in dollars. So, say you'd invested $1,000 in each. $1,000 in ABC buys you 40 shares. $1,000 in XYZ buys you 20 shares. Their EPS adds that buck, the shares rise to maintain P/E, and you have: ABC: $6 EPS at P/E 5 = $30/share. Position value = 40 shares x $30/share = $1,200 XYZ: $6 EPS at P/E 10 = $60/share. Position value = 20 shares x $60/share = $1,200 They both make you the exact same 20% profit. It makes sense when you think about it this way: a 20% increase in EPS is going to give you a 20% increase in price if the P/E is to remain constant. It doesn't matter what the dollar amount of the EPS or the share price is." all other things being equal if you have two stocks, both with a P/E   of 2, and one has an EPS of 5 whereas the other has an EPS of 10 is   the latter a better purchase? What this really boils down to is the number of shares a company has outstanding.  Given the same earnings & P/E, a company with fewer shares will have a higher EPS than a company with more shares.  Knowing that, I don't think the number of shares has much if anything to do with the quality of a company.   It's similar to the arguments I hear often from people new to investing where they think that a company with a share price of $100/share must be better than a company with a share price of $30/share simply because the share price is higher. "Check your math... ""two stocks, both with a P/E of 2 trading at $40 per share lets say, and one has an EPS of 5 whereas the other has an EPS of 10 is the latter a better purchase?"" If a stock has P/E of 2 and  price of $40 it has an EPS of $20. Not $10. Not $5."
How to find good divided stocks? Research and read. Google, Yahoo, and most likely your broker offer some sort of stock screener tool where you can look for stocks with given P/E ratios, dividend payouts, pricing, and any of a number of other filters. When you've found some that appeal to you, read what others are saying on stock talk websites like Vantagewire and Stockhouse. Read what each company is putting out as news and look at their quarterly reports. In Canada you can find a company's reports for free on Sedar. I'm afraid I don't know the U.S. equivalent. Reuters will be of help. Finding a good dividend-paying stock is the same as finding a good growth or value stock; research the company and the sector as if you were buying it to take the company over. The P/E ratio is a measure of historic (the previous financial year) earnings against the current share price. If the P/E is high, this means that the market perceives a big increase in future earnings per share.  In other words, the perception is that this is a fast growing company.  Higher earnings may also equate to big increases in dividends and rapid expansion.  On the other hand, if the P/E is low, then there is a perception that either earnings per share are decreasing or that future growth in earnings is negligible.  In other words, low P/E equates to a perception of low future growth and therefore low prospects for future payout increases - possibly even decreases. The market is (rightly) usually willing to pay a premium for fast growing companies. "Here is how I would approach that problem: 1) Find the average ratios of the competitors: 2) Find the earnings and book value per share of Hawaiian 3) Multiply the EPB and BVPS by the average ratios. Note that you get two very different numbers.  This illustrates why pricing from ratios is inexact.  How you use those answers to estimate a ""price"" is up to you.  You can take the higher of the two, the average, the P/E result since you have more data points, or whatever other method you feel you can justify.   There is no ""right"" answer since no one can accurately predict the future price of any stock." "For free, 5 years is somewhat available, and 10 years is available to a limited extent on money.msn.com. Some are calculated for you. Gurufocus is also a treasure trove of value statistics that do in fact reach back 10 years. From the Gurufocus site, the historical P/E can be calculated by dividing their figure for ""Earnings per Share"" by the share price at the time.  It looks like their EPS figure is split adjusted, so you'll have to use the split adjusted share price. ""Free cash"", defined in the comments as money held at the end of the year, can be found on the balance sheet as ""Cash, Cash Equivalents, Marketable Securities""; however, the more common term is ""free cash flow"", and its growth rate can be found at the top of the gurufocus financials page." This is only a rule of thumb. Peter Lynch popularized it; the ratio PE/growth is often called the Lynch Ratio. At best it's a very rough guideline. I could fill up this page with other caveats. I'm not saying that it's wrong, only that it's grossly incomplete. For a 10 second eyeball valuation of growth stocks, it's fine. But that's the extent of its usefulness. PE ratio is the current share price divided by the prior 4 quarters earnings per share. Any stock quote site will report it. You can also compute it yourself. All you need is an income statement and a current stock quote. Usually their PE ratio will just be listed as 0 or blank.  Though I've always wondered why they don't just list the negative PE as from a straight math standpoint it makes sense. PE while it can be a useful barometer for a company, but certainly does not tell you everything.  A company could have negative earnings for a lot of reasons, some good and some bad.  The company could just be a bad company and could be losing money hand over fist, or the company could have had a one time occurrence such as a big acquisition or some other event that just affected this years earnings, or they could be an awesome high growth company that is heavily investing for their future and forgoing locking in profits now for much bigger profits in the future. Generally IPO company's fall into that last category as they are going public usually because they want an influx of cash that they are going to use to grow the company much more rapidly.  So they are likely already taking all incoming $$ and taking on debt to grow the company and have exceeded all of those options and that's when they turn to the stock market for the additional influx of cash, so it is very common for these companies not to have earnings.   Now you just have to decide if that company is investing that money wisely and will in the future translate to actual earnings. "Some companies have a steady, reliable, stream of earnings. In that case, a low P/E ratio is likely to indicate a good stock. Other companies have a ""feast or famine"" pattern, great earnings one year, no earnings or losses the following year. In that case, it is misleading to use a P/E ratio for a good year, when earnings are high and the ratio is low. Instead, you have to figure out what the company's AVERAGE earnings may be for some years, and assign a P/E ratio to that."
