I like the term "investing using Black Scholes", whatever that means. Anyway...
No need to be patronizing about it. I know Black Scholes is just a formula for derivatives valuation.
I just mentioned it that way cos Turnevies used it.
By "investing using Black Scholes" im just using it as an umbrella term for investing using any mathematical models and economic models and such, espl micro economic models.
Even for a hedge fund, with a bunch of PhDs in mathematics and a good infrastructure with low trading costs, it is very hard to consistently outperform the market.
You are reiterating the exact point i made, and yet it seems that you disagree with me.
As someone working in a hedge fund doing systematic trading with equities, I can say this about the stock market: if you are looking at the market from the perspective of having read a couple of books, and even a lot of academic papers, the market will indeed look efficient.
However, it is a huge joke to say that the markets are efficient. For example, I was recently shocked by the miscalculation the whole market did of the probability of Brexit. The market can be quite stupid, but one needs to do *a lot* of disciplined research, and think extremely critically about your own hypotheses about the market. You also need a lot of creativity. If an idea is in a book, it probably doesn't work anymore. Basically you have to outwit a lot of people in the market who themselves are trying to outwit everyone else.
I didnt want to go into a theoretical discussion into efficiency. Of course there are several studies to suggest both efficiency and inefficiency.
My reply was to OP who isnt very financially literate so i replied to him in very informal terms.
Yes the market isnt perfectly efficient, but is it efficient enough for a non-finance expert to be able to beat the market consistently?
I think so
And, yes i havent worked in investment. Ive only worked in actuarial teams, i was initially inclined to transition to investment banking later, but lost interest in it.
My knowledge only comes from academics. But facts are facts nevertheless.
I personally see no other approach to investing other than having a broad and deep understanding of the economy and the markets. Only then can one start doing good decisions about where to put money.
This is where the key question comes.
Should OP spend the time and effort to study concepts worth years of learning or rather focus on some other investment alternative?
There is a cost to gathering information, how many years of reading do you think it would take OP to be able to actually make accurate investment decisions such that he is able to meet his financial needs better by active investing than passively putting them in a bank?
Also, dont forget the costs of learning directly as in getting your hands burnt initially, is the risk really worth it? Is the time worth it.
If OP wants to learn concepts and wants to do it as an interest, nothing matters. But if OP wants to learn stuff to actually get greater returns, then i would be inclined to say that the cost-benefit doesnt work out.
OP would probably be better off in spending the time in:
a. Improving his skillset in his native profession, or a new one
b. Investing based on special information OP might have, which are local businesses and local real estate.
imo, the cost of learning plus the cost of being updated in the financial sector is too high to be worth it unless you are pursuing a career in it, and in the absence of an environment to readily receive information and quickly analyse it, i feel it just gets worser
If OP has any surplus funds imo hes better off putting it in a savings account or fixed interest securities where atleast the nominal values are more or less guaranteed and is more likely to match OPs life requirements, as in my opinion any effects of inflation and macro economic changes will probably be matched by reduction in prices of OP's needs
That is exactly what i suggested and i stand by that
