The chart says 2nd, 4th to 6th, 9th to 14th, 16th to 21st and 25th to 28th seem to be good choices in buying UITF. My previous and ongoing investment, which falls on every 15th, is unfortunately one of the peaks of average prices. I chose 15th due to cash flow considerations and I did not think of doing this exercise in Jan2013. Just now. Hindsight.
