Suppose one expects that IPOs, on the whole, show poor performance following the IPO (especially if one buys at the IPO), and wishes to bet against them.
This can be done by simply shorting every IPO (assuming someone can be found who will lend the shares), and then covering after 6 months, or for instance setting a limit at -10% and a stop at +20%. But between the borrowing fees and commissions, this does not seem practical for a small trader.
One could also buy puts, or some sort of bearish combination. However for a new stock the liquidity will be poor (for instance PTHN was a month ago and still has only a few dozen open interest). Options are also an advanced instrument so again not very practical.
If one's outlook is that IPOs generally tend to decline after the IPO, is there an easy way to profit from this thesis?
