I would not say that such mathematical or statistical models are just academic and have no place in real investing. I think it was Munger who said that, for a person with a hammer, everything looks like a nail. I would say the opposite statement also has merit, that if you give someone a stick and a rock, a hammer can be made. My point is, it all lies in the application, the execution, some techniques or models have clear limitations, but some may have more applications than one has imagined. There really are many ways to skin the cat, if that is not true, I wouldn’t be here, I would have left the arena long time ago. But no, there is a place for me too, provided if I am open to ideas every which they come, learn, practice, adapt etc.
Another aspect is that, this is all personal finance. It is personal first and finance next. Each one’s context is different. So excluding the basic and broad guidelines that can be learnt from Freefincal, everything else has a clear context. So a choice of investing taken out of that context may appear as meaningless or academic, but they appeal to readers who are in the similar situation. Priorities are different.
I will give my personal perspective again that, a financial goal is one that comes with price tag and a deadline. It has to happen at a particular point in our life, and as it has to do with finance, inflation has to be accounted for, and a final figure has to be arrived at. There is no subjective argument here. Wealth is subjective, for someone an 8 digit number is wealth, for someone a 10 digit number is wealth. I invest in stocks for this, to create a bit of wealth, along with the notion of thinking the PF to be a house or a plot that can be given to successors. I take chances here, I learn, make mistakes, try to correct them, make no big mistake that will takes me off the market etc.
We can invest in stocks for goals, sure but I am not sure if one can be mechanical and emotionless with stocks. Say I expect 15% return from a stock PF which I intended to sell after 10 years for a goal, and if a particular stock performs well exceeding my expectations, and when the goal’s time has come, if I am in such a position that my goal will not be realized unless I sell the best performing stock, what would I do? I know that it has a very good chance of going much higher from here, and it will be foolish to sell the stock considering the low price I have paid. In other words, if because of any bias, I bring myself to not selling the stock and doing something else to realize the goal, which derails other plans. So I would like to keep financial goals and adventures separate. MFs don’t have a problem like this, and I think it does not make a person feel that he is losing ownership. So as the time progresses, and if I reach 80% of my target corpus, I would gladly sell the funds and move to debt, and the goal will be realized irrespective of the market.
I personally feel that, investing for any financial goal including retirement is relatively easy compared to reading an AR of a company. It is all about a number, that gives a guarantee to the lifestyle that one envisages to have in the future, but that number should be arrived after incorporating a lot of choices one makes up to that point, say for example a person wants to retire in the city he works, starts with a plan, a few years down the line he may want to move abroad or go back to his hometown, or the initial idea is to retire at 65, it may happen soon etc. Not to mention the post-retirement activities that one wants to participate in. So retirement planning in that sense does not come with a concrete framework, it is both quantitative and subjected to changes as time passes.
So if one is absolute regarding these aspects, then I guess, it is the matter of a number. Once we arrive at that number, then we can see if one can reach that number with MFs alone if the return required is 12%, or it demands 18% hence stocks, or even debt products if the return needed is 7%.
Math part is easy, in the sense that, it does not change with our thoughts, so once we settle down with our thoughts, we can work on math, and can see what can be done to make it come true.
And I am yet to invest for any specific goals, so I am yet to experience the kind of activity that should do or not do during the tenure of the goal, so take my advice regarding this one aspect with a lot of salt.
On a side note, retirement planning is the primary goal for Freefincal’s professor. Your situation may be in complete contrast with him, but the goal is the same, retirement planning. So if you go through the posts again with this in mind, perhaps you can see another angle in those posts.
