1. Stock price remains the same but revenue doubles.
2. Revenue stays the same, but stock price doubles.
Assuming all else equal, and recognizing that this is absolutely a simplification, but if these were the two choices then it seems a no brainer that you'd go with option 2. Revenue is a means of increasing stock price.
If you're holding MS stock long-term, and you plan to gradually shift away from equities as you near retirement and then gradually liquidate your holdings to fund your retirement, juicing the stock in the short term does nothing for you.
If you're holding short-term, then you also need to sell the stock after it gets juiced, so that you can move your capital to not-yet-juiced stocks.
