The key to stocks has nothing to do with such minimal rises or drops in price. "The toilet" is not defined by a 6% cumulative drop in value. If Apple is a company whose future prospects you have strong faith in, the price drop means the stock is on sale for 6% off in the last 2 days. The last couple months have been outstanding times to buy. Price drops in stock value for strong companies are nothing more than buy opportunities for long-term holds unless something economically or otherwise changes that may make holding the stocks a bad idea (large lawsuits, poor products introduced, large financial losses, etc.).
Every time the market takes a nose dive is an excellent time to buy. People see the market topping out above 15,000 and all of a sudden want to get in on the ride. That's probably the worst time to ever buy stocks unless one you are particularly interested in is selling for a perceived value.
If someone told me my favorite stock dropped a good percentage and their future looked bright, I'd be all over buying its stock. "In the toilet" for Google, Apple, Exxon Mobile, AT&T, Verizon, etc. would be good timing for buying in, not running in fear. Conversely, if the price drop were on a shaky company with poor financials and little future outlook for growth and value, that's when you worry and get out if the future looks really weak long-term.
To add to smdbills excellent commentary, fluctuations like this are often the result of short term buying and selling. Those of us in the buy and hold camp buy when we think price is right and hold until we're ready to sell. I bought some Apple stock recently because I thought it was near a bottom. Maybe I missed the actual bottom by a few dollars but I think it will increase greatly over the next year or two.
