Consider an investment in a company like Tesla as an investment in real brick & motor, machines and knowledge of people. What you bought is not a piece of paper like money with an associated promise for exchange but something you can touch and that creates a margin and profit.
Now in your example with the money stolen you lost the document that enables you to exchange the promise into services or products.
For Jane, she still owns the same amount of assets like before only if she wanted to exchange this for a paper promise (Money) today she would get less of it.
Its two fundamental different things and I suggest if you have an issue to follow that thought, which is totally fine and no offense, consider to stop investing the stock market because the likelihood that you will loose money on the long run is exceptional high.
Responding in side thread so as not to derail the main one.
They’re the same because Fred bought Tesla after his “real loss”. They both own 10 shares of Tesla.
You have to separate the loss at the time it’s being called a loss, from any future actions. That’s specifically why I had Fred buy 10 shares of Tesla in my example. I wanted to remove any difference in subsequent actions, so that we can zero in on the point in time for the loss.
What in the world are you talking about me needing to stop investing for? Just because I realize my net worth is down by 25% in less than a month, does not mean I’m dumb. I was gradually de-leveraging during the rise to reduce my risk profile. I’m gradually re-leveraging during this drop, including this morning when I bought 20 TSLA shares. I’m debating how much to buy and at what points if the stock falls more. I probably should not buy more considering my risk is already somewhat higher than it should be, but it’s hard to resist.
Are you serious that you believe pretending share price drops are not real losses, is a good technique for investing?
I’m saying drop the psychology and invest based on risk profile and an assessment of what will happen going forward. Pretending share price drops are not real losses, or pretending that just because you have a low cost basis, you haven’t lost money is bad logic and can lead to bad decisions.
Pretend the money is in a tax free account and one investor holds 100 shares he purchased at $30, and another investor holds 100 shares purchased at $900.
Fact 1) They are in the same place. They both own 100 shares of Tesla. It’s irrelevant that one used to have a net worth of $3k and increased it to $60k, or that the other had a net worth of $90k and saw it decrease to $60k.
Fact 2) One should not make decisions differently than the other because the cost bases are different. Regardless of how they started out, they both are now in the same position. All decisions should be based on whether Tesla is a good investment going forward, relative to other investment opportunities.
Fact 3) With the share price at $600, they both have had real losses of $30k relative to their net worth when the share price was $900.
Fact 4) If the Investor who bought at $900 sells TSLA today at $600 that is not “locking in a loss” relative to the other. Maybe that investor purchases shares in a Genomic breakthrough company that does even better than Tesla. Maybe he gambles it in Vegas and loses it all. It doesn’t matter. They both have lost $30k as of today.
The point is share price drops change your net worth and are REAL. The only thing that matters is how you process the loss and respond to it, whether that response is selling shares and buying call options, holding fast, or selling shares and going to Vegas, selling other stocks and buying more Tesla... You have to separate the loss that occurred from what future actions should be taken.
