Is 'days to cover' a useful metric in identifying the potential for a short squeeze?
SeekingAlpha has an article about short squeezes that states: The higher the number of days to cover means the possibility for a short squeeze is greater, and the potential size of the short squeeze is also greater Logically, this makes sense. A short squeeze occurs when a lack of supply meets excess demand for a stock, so the potential for a squeeze increases when supply and demand begin to get out of equilibrium. Think of two things that would cause the days to cover to increase and what effect they would have on supply and demand.  The current short interest (numerator) increases. This implies that if some event triggers short sellers to cover their position, there are a higher number of short sellers who will need to do so. This heightens the chances that demand will exceed supply.  The average daily volume (denominator) decreases. This implies that fewer investors are trading the stock, so if an event triggers short sellers to cover their positions, there might not be enough traders in the market willing to sell their shares. (Obviously, if a short-squeeze occurs, volume may increase because traders who were unwilling to sell their shares become willing).
It is a general truism but the reasons are that the rules change dramatically when you simply have more capital. Here are some examples, limited to particular kinds of markets: Under $2,000 in capital Nobody is going to offer you a margin account, and if you do get one it isn't with the best broker on commissions and other capabilities. So this means cash only trading, enjoy your 3 business day settlement periods. This means no shorting, confining a trader to only buy and hold strategies, making them more dependent on luck than a more capable trader. This means it is more expensive to buy stock, since you have to put down 100% of the cash to hold a share, whereas someone with more money puts down less capital to hold the exact same number of shares. This means no covered options strategies or spreads, again limiting the market directions where a trader could earn Under $25,000 in capital In the stock market, the pattern day trader rule applies to retail margin accounts with a balance under $25,000 and this severally limits the kinds of trades you are able to take because of the limit in the number of trades you can take in a given time period. Forget managing a multi-leg option position when the market isn't moving your direction. Under $125,000 in capital Worse margin rules. You excluded portfolio margin from your post, but it is a key part of the answer Over $1,000,000 in capital Participate in private placements, regulation D offerings reserved for accredited investors. These days, as buy and hold investments, these generally have more growth potential than publicly traded offerings. Over $5,000,000 in capital You can easily get the compliance and risk manager to turn the other way on margin rules. This is not conjecture, leverage up to infinity, try not to bankrupt yourself and the trading firm. My guess would be in the short term, local small businesses around these big-boxers get squeezed from rising wages, but in the long-run, they're still playing Amazon's game. And yet, it's the small retailers that don't have to get caught up in the Amazon race. Matt Levine talked about a cute scam that this resembles, a kind of extended short squeeze. You manipulate up the stock of a company, so that it's obviously way above the fundamental value. Word will get out. Then the shorts come in. But the value remains stubbornly high. All the stock is held by a few insiders, but they didn't manipulate the stock price to do a pump and dump. They did it to milk the shorts on borrow cost. "There are a number of strategies using options and shares together.  One that sells large potential upside gains to assure more consistent medium returns is to ""write covered calls"".  This fairly conservative and is a reasonable entry point into options for an individual investor. Deeper dive into covered calls" I would go even farther than Victor's answer.  There is little evidence that candlestick patterns and technical analysis in general have any predictive power.   Even if they did in the past, of which there is some evidence, in modern times they are so easy to do on computers that if they worked algorithmic traders would have scanned almost all traded stocks and bought/sold the stock before you even had a chance to look at the graph. While the best technical traders who are very good at quickly using pattern recognition across many indicators as Victor mentioned might be able to add some advantage.  The odds that a pattern so simple to code such as Bullish Engulfing would have predictive power is tiny. "I think it's apt to remind that there's no shortcuts, if someone thinks about doing FX  fx: - negative sum game (big spread or commissions) - chaos theory description is apt - hard to understand costs (options are insurance and for every trade there is equivalent option position - so unless you understand how those are priced, there's a good chance you're getting a ""sh1tty deal"" as that Goldman guy famously said) - averaging can help if timing is bad but you could be just getting deeper into the ""deal"" I just mentioned and giving a smarter counterparty your money could backfire as it's the ""ammo"" they can use to defend their position.  This doesn't apply to your small hedge/trade? Well that's what I thought not long ago too! That's why I mentioned chaos theory. If you can find a party to hedge with that is not hedging with someone who eventually ends up hedging with JPM/Goldman/name any ""0 losing days a year"" ""bank"".. Then you may have a point. And contrary to what many may still think, all of the above applies to everything you can think of that has to do with money. All the billions with 0-losing days need to come from somewhere and it's definitely not coming just from couple FX punters." A shorter term MA would be used for short term changes in price whilst a long term MA would be used for longer term movements in price.  A 200 day SMA is widely used to determine the trend of the stock, simply a cross above the 200 day SMA would mean the stock may be entering an uptrend and a cross below that the price may be entering a downtrend. If the price is continuosly going above and below in a short period of time it is usually range trading. Then there are EMAs (Expodential Moving Averages) and WMAs (weighted moving averages) which give more emphasis to the latest price data than the earlier price data in the period chosen compared to a SMA. MAs can be used in many different ways, too many to list all here. The best way to learn about them is to read some TA books and articles about them, then choose a couple of strategies where you can use them in combination with a couple of other indicators that are complimentary with each other. There are lots of good answers on here already.  There are actually lots of answers for this question.  Lots.  I have years of experience on the exchange feed side and there are hundreds and thousands of variables.   All of these variables are funneled into systems owned by large financial institutions (I used to manage these - and only a few companies in the world do this so not hard to guess who I work for).  Their computers then make trades based on all of these variables and equations.  There are variables as whacky as how many times was a company mentioned in an aggregate news feed down to your basic company financials.  But if there is a way to measure a company (or to just guess) there is an equation for it plugged into a super computer at a big bank. Now there are two important factors on why you see this mad dash in the morning: Now most of the rest of the day is also automated trades but by the time you are an hour into market open the computers for the most part have fulfilled their calendar buys.  Everyone else's answer is right too.  There is futures contracts that change, global exchange info changes, options expiring, basic news, whatever but all of these are amplified by the calendar day changing.
