rather than pick out individual stocks to trade, it can often be worthwhile to trade the indices themselves, especially in times of high volatility.
for those so inclined, i attach below charts for FTSE and FTSE 250, though one might equally be tempted to trade Dow or S&P, which is significantly broader in its coverage, or even NASDAQ
for ease of reading, i have attached 1 year and 3 month charts in each instance
