What happens if the stock price is below the strike price?
If the stock price remained below the call strike price of $60, the investor would keep the options premium. Should the stock price exceed the strike price at expiration, the investor could allow the stock to be sold at $60, or perhaps buy the callback and “roll” to a higher strike price in a more distant month.
Is wealth created by concentrated positions and preserved by diversification?
The constant challenge, and concern, is diversifying the risk of having all, or most of, one’s eggs in one basket. As the old saw goes, wealth tends to be created by concentrated positions and preserved by diversification.
What is concentrated stock?

What happens if you work for a concentrated company?
If you still work for the company of the concentrated position, your job could be at risk at the same time the stock loses value. Having your income and wealth in one company puts a lot of eggs in one basket. As such, investors generally should reduce their holding in a concentrated stock position to lessen these risks.
How to reduce stock holdings with capital gains?
Gifting is a great strategy for reducing stock holdings with capital gains. A popular choice is gifting stock directly to non-profit charities. By donating stock instead of cash, you reduce your stock position and are likely to receive a tax deduction. Donors are eligible for an income tax deduction for the full market value of the stock, up to 30% of adjusted gross income. You benefit by reducing your position and capital gain exposure, and the charity benefits by selling the stock while paying no tax because it is a non-profit. Everyone wins!
What happens if the original stock exchanged outperforms the fund?
Also, if the original stock exchanged should outperform the fund, the investor is stuck with the fund value – you can’t have your cake and eat it too. Lastly, the investor still keeps the original cost basis of the stock with the new fund position, though the need to sell is less due to diversification.
What happens if your stock drops in value?
