How to take a defensive posture? Mark Minvervini gave us details:

1. Get off margin immediately
2. Raise at least 25-50% cash
3. If you choose to trade, take smaller than normal position sizes
4. Reduce overexposure in any one industry group and diversify more broadly
5. Reduce exposure to high beta stocks
6. Avoid laggard stocks (even if they look cheap)
7. Nail down profits when you have them (be less greedy)
8. Tighten up your stop-losses (be less forgiving)
9. Sell all stocks that break down in price (especially if they can’t rally)
10. Upgrade in quality and reduce exposure to low priced stocks
