From the Lessons Learned article posted a few days ago, in order to gain higher returns, the investment model needs to have greater dispersion with my buy/sell trigger points in its model. Last year, the buy/sell triggers for Union Pacific were a 17% market price decrease from the prior peak and to sell at 100% of prior peak.
This purchase point is driven by the model update whereby market price decreases must hit 18% decrease and the sell point increases to 102% of the prior peak price. This post covers the model update and the associated dollar amounts tied to Union Pacific.
