Yes, the potential lose is unlimited if selling uncovered call while the
stock goes up crazy.
If you have some margin to use, in the bull market, it is fine to sell some
put. The worst case is you buy back stocks at relative lower price.
The way to protect current position is very tricky. For example, if you have
AAPL and worrying about short term pull back. One of protection is: Sell
390 call, and use the premiums to buy 340 and 300 put spread. The cost is
about 1 dollar, but it give you about $50 downside protection.
