I'm starting to contemplate at what price I will resume accumulating shares. BFPT was very helpful to me in the past. But we have undergone fundamental change in how the market perceives Tesla, so the BFPT will not be well calibrated for about a year.
Within my IRA, my strategy has been to sell off excess shares as the value of my position rises above a certain upper value limit (UVL). The last price I sold at way $500. The proceeds I have reinvested in other stocks that I believe have a material chance of beating Tesla over the next year. My intent has been to hold this UVL until the non-Tesla portion of my portfolio becomes substantial. But we could be faced with a 20% to 30% pullback. This also means that the value of my Tesla position falls 20% to 30% below my UVL. So the question I'm asking myself is whether I want to set some lower value limit (LVL) below which I accumulate more Tesla shares. This means I would be trading to keep the value of my Tesla position between my LVL and UVL. So I'm thinking about setting LVL to 0.8*UVL, but 0.7*UVL might also be reasonable. The choice here would seem to depend on volatility and how much trading I want to do. Since this is in an IRA I don't have to worry about capital gains or other trading costs.
Any suggestions?
Depends on your valuation of Tesla's future. Based on what you wrote it appears that you believe other stocks in your portfolio have higher growth potential than Tesla. You should come up with a target number for those stocks and also for Tesla. If Tesla drops to a level where it's undervalued and has a better chance to make you more money then that's where your LVL limit should be.
Something to contemplate is setting a LVL (say .8*UVL) and mapping out when you'll buy back. Will you buyback immediately and with enough dollars to maintain the LVL or would you dollar cost average and setup something like initiate buys of X dollar amount per day to DCA when the stock is below your LVL.
Also, think about adjusting your UVL to better take advantage of upward price movements. Instead of immediately selling to cap your UVL have it set off a sell program. For example once your UVL is hit maybe come up with X dollars in value to sell per day until the total value is below your UVL.
Personally I think TSLA will grow to be the most valuable company in the world within ten years so my UVL is infinity and my LVL is equal to current value: ie. buy at any price up until the year 2030.
