RE: Sell in May & .......Having a plan to sell at some point is pretty good idea. When to sell depends on what sort of investor you are. Sell in May is historically a seasonal beginning for softer equity markets in general. Your investments are best decided by their own charactaristics and their own specific longer term trend lines. MKR has interesting gold values and base metals also, so you could follow several of the commodity indexes and gold for trend line strength going into the end of May. All commodities will have a softer period, including gold, but seems IMHO these things are just breaking out from consolidation periods. That does not mean that by June they won't be ready for rest. It depends also on type of investor you are. If you sell all your position in May based on "seasonality factors" alone, that might put you out of the share prices and not necesarily guarrantee a lower buyback. When the trend is exhausted ( intermediate trend ) there will be topping patterns and activity that suggest that.
good luck in your investing
