This week we will have a rare Quadruple Witching Friday. That is where contracts for stock-index futures, stock –index options, individual stock options and individual stock futures all expire.
What that means for the stock market is more volatility. So this week we will see options buying and corporate buyback flows as a likely result, but following this week the blackout period for stock buybacks will put downward pressure on stock prices.
So expect a wild ride for this week and next. Of course no one ever knows what investors will do but history is a great teacher and it tends to repeat itself.
