Despite their healthy looking charts, GOOG and MA, have a tendency to trade with a trailing PE below 20 during times of economic slowdown fears. With fears of a severe slow down, MA traded with a multiple near 17, and GOOG near mid 16. QCOM's chart is not as healthy, but has the same tendency.
GOOG current trailing PE: 21 (There are a slew of technical support, but the 50SMA may be the most plausible.)
MA current trailing PE: mid 20 (The 62 seems like a plausible support. MA is already on the current 38SMA support, not pictured. The 38SMA is what supported MA at the end of Nov.)
QCOM current trailing PE: 21.11 (I am not sure how low QCOM can go. 49-50 seems reasonable depending on any potential market negativity.)
