This strategy is based on bottom fishers strategy. This looks for oversold stocks where the downward pressure is lesser than potential for trend reversal.
We try and restrict the downside by combining fundamental expectation and technical score. Choosing stocks with more than 25% fall from 52 Week high implies that these stocks have recently fallen out of favour. By combining the analyst expectations we try and find stocks which have been punished more than they deserved.
Pro tip: An empty set or very few stocks in the screener implies that the market is over heated in general.
