Are there common stock price trends related to employee option plans?
There's an odd anomaly that often occurs with shares acquired through company plans via ESPP or option purchase. The general situation is that the share value above strike price or grant price may become ordinary income, but a sale below the price at day the shares are valued is a capital loss.  e.g. in an ESPP offering, I have a $10 purchase price, but at the end of the offering, the shares are valued at $100. Unless I hold the shares for an additional year, the sale price contains ordinary W2 income. So, if I see the shares falling and sell for $50, I have a tax bill for $90 of W2 income, but a $50 capital loss. Tax is due on $90 (and for 1K shares, $90,000 which can be a $30K hit) but that $50K loss can only be applied to cap gains, or $3K/yr of income.  In the dotcom bubble, there were many people who had million dollar tax bills and the value of the money netted from the sale couldn't even cover the taxes. And $1M in losses would take 300 years at $3K/yr.  The above is one reason the lockup date expiration is why shares get sold. And one can probably profit on the bigger companies stock.  Edit - see Yelp down 3% following expiration of 180 day IPO lock-up period, for similar situation.
