# My investment strategy (detailed version)

PE reference Yahoo finance's QQQ (with the historical percentile of NDX's PE and PB in the leek circle as auxiliary)

①Weekly fixed investment in TQQQ

②Sell TQQQ's PUT options with 3~6 months left (choose the one with higher annualized yield)

Note: Because the annualized yield is relatively low when the time is too short or too long. The calculation formula is: annualized yield = (option transaction amount ÷ target price) × (365 ÷ remaining time of the option), which can be directly viewed in some brokerage apps (Figure 1), but there is a slight difference from the calculated result, for reference only

③The selection idea of selling options at what price

(1) Sell QQQ's PUT option X at the price calculated when PE=30, this X represents the amount required for exercising this strike price option

Calculation method: Take the current example, QQQ's PE on Yahoo finance is 33.75, then when PE is 30, TQQQ's price is approximately (1-((33.75-30)÷33.75)×3))×TQQQ's current closing price 86.75=57.83, this is a linear calculation result, but TQQQ's rise and fall are exponential changes, and this price deviates more as QQQ's PE increases, because in both unilateral rise and fall, TQQQ has the characteristic of 3 times in a single day, which will cause TQQQ to grow exponentially in unilateral rise (Figure 2), and also has this characteristic in the fall process (Figure 3), this is a simple example (Figure 4), that is, whether it is unilateral rise or fall, for TQQQ it is better than similar 3 times leveraged financing QQQ, this characteristic is also beneficial for TQQQ's investment.

Then we should multiply a rough coefficient in the above calculation, I simply asked AI, simulating a unilateral fall where QQQ falls 1% every day, when it falls 10% 20% 30%, TQQQ falls about 27% 49% 66% respectively, the coefficient is about 0.9, 0.82, 0.73. For example, at this time QQQ's PE is 33.75, falling to PE=30, then it fell 11.11%, then the coefficient we take is about 0.9, then when PE=30, TQQQ's price is about (1-((33.75-30)÷33.75)×3×0.9))×TQQQ's current closing price 86.75=60.725, you can choose to sell PUT options at 60, of course we can also directly ask AI, under what percentage QQQ falls, TQQQ may fall what percentage (need to assume unilateral market).

(2) PE=25 price. PUT 2X. PE fell 25.93%, consulting AI got TQQQ's price fell about 59.7%, then TQQQ's price is 35, you can choose options at 35

(3) PE=20 price. PUT 4X. PE fell 40.74%, consulting AI got TQQQ's price fell about 79.5%, then TQQQ's price is 17.78, you can choose options at 20 or simply not sell this PUT, keep cash for future opportunities to sell PUT at 17

Note: X is the amount required to receive shares after the option is exercised, 7X=non-leveraged market value ÷ 2 + US short-term bonds or cash (varies from person to person)

(4) Every time TQQQ reaches 100 shares, sell 3~6 months (choose the one with higher annualized yield), PE=35 price CALL, the exerciser buys QQQM. TQQQ's price is the same as above, for example, now PE=33.75, then when PE=35, PE rises 3.7%, TQQQ rises 11.48%, TQQQ's price is about 96.71.

⚠️⚠️⚠️Note: The above are simulation calculations, the actual situation cannot be monotonically rising or falling, and PE will change with the company's financial reports, the above is only personal thinking, not investment advice.
