2010 Has been a good year, but here are my biggest mistakes. All classics which I could have avoided. I hope to do better next year.
Listed by symbol, and lesson learned.
IOC/BYI - Avoid large risk/reward situtions avoid shorts / options, they don't work for me
TTT Stay with corp actions through the process completion and allow time for capital structure to stabilize
IPGP/INFN - Monitor gains and trim positions that grow above 5%
DSWL - Monitor losses to validate/reject the original investment assumptions
DSWL - Avoid obscure companies with poor track record even if PE/Div / price book
look good, bad management!
LYG - don't buy on impulse, do solid research and analysis EVER TIME
CML - Take calculated risks and stick with them see below
CML - For growth/tech type positions, be prepared to stick with them if they are potential acquisition targets
Good luck in 2011
