Worksheet Answers

1.
Option B

Solution:

Everyone has ambitions so that's not a sign of being fundamentally strong.

Having no competition just means that you have not been tested yet and any day a competitor arrives in the market, the perception about the first company can change very quickly.

Fundamentally strong companies have robust revenue and profit growth, along with a strong balance sheet. An example of fundamentally stong company would be Hindustan Unilever (as of 2018).

9.
Option C

Solution:

Face value is only useful in calculating dividends so it has no importance for traders. Book value is kinda important from valuations perspective but the most important valuation the trader is concerned with is what the market attributes to it.

11.
Option B

Solution:

When revenues are going up but profitability isn't, it means that the company is facing margin pressures. A typical example would be TVS Motors. It has a steadily increasing revenue but its margins are always under pressure. The day they start improving their margins, the stock would move like a rocket.

17.
Option C

Solution:

There are broadly two types of companies: Product based and Services based. A product based company typically makes physical products (anything that you can touch and feel) whereas a services based company provide sevice like banking or IT consulting. The above mentioned company had no raw material expense there it can not be a product based company.

The only exception to the above classification is software product based companies like Microsoft, Oracle etc., which are product based companies but their products can't be touched.

BTW, the company in question is TCS.
