StockCharts' Keller: 'Nothing good happens below the 200-day moving average'

David Keller, chief market strategist at StockCharts.com -- the president, Sierra Alpha Research -- says that until the stock market can get above its long-term trend line and show fundamental strength, investors may want to question how good things are really getting. Keller notes that there are plenty of reasons for optimism, but 'the proof is in the price,' and he will stay skeptical until the major benchmarks follow through on major barometers. Keller notes that the 3,800 level on the Standard and Poor's 500 is a key level to watch, as if the index drops below that level -- the low from December -- it could unleash some negative probabilities that investors may want to plan for. In The Big Interview, Paul Espinosa, lead manager of the top-rated Seafarer Overseas Value Fund, discusses why international markets and especially emerging markets are priced right for a rally, even as they digest issues ranging from war to inflation and more.
