Key to understand future lies in the past. To understand this concept let us draw an analogy between Universe and Mathematics. With time universe is expanding and it began from nothing when energy and mass was single entity, as per big bang theory. Let us consider the beginning of universe as point zero and one side of expansion as positive leading to +infinity and other side of expansion as negative leading to -infinity. Now let us assume mathematical numbers also expanding with time, starting from zero towards +infinity and -infinity.

Now consider every event in universe is unique and represented by each number. As we all know that each number is unique and not repeatable but there are some properties which are repeatable like we can categorize them in odd, even and prime numbers. For even numbers we know that every even no is divisible by 2, for prime nos we know that it is not divisible by any no. Like this we have every no as unique but some properties are rhyming. Similarly, we can understand that every event in this universe is unique and not repeatable but rhyming. So, we can understand that history does not repeat itself but it rhymes itself. Similarly, stock market is always new but we still can find some repeatable properties pertaining to some patterns and can use them to take well informed and mathematically calculated decisions.
