Can this person have cash flow problems? It's unclear. This is the disadvantage of the cash flow statement, as it doesn't provide information on the sufficiency of cash flow. To address this limitation, I use the PR%. The numerator of the PR% is the increase in fixed assets and long-term investments (representing investment activities), and the denominator is net earnings, which is a crucial component of operating activities. The PR% is calculated as investment activities divided by operating activities. In this example, with a monthly salary of $10,000 and stocks purchased at a cost of $12,000, the PR% is 120%. This indicates that the cash flow is sufficient, as a $2,000 shortfall can easily be borrowed. An PR% of 100% means that the salary and stock purchases are equal, providing sufficient cash flow.

How much difference is considered dangerous?
Having a 200% PR% by investing $200,000 in stocks with a monthly salary of $100,000 is considered dangerous.
There are two potential outcomes:
One is embezzlement,
the other is investing in an industry with aggressive expansion,
such as DRAM and LCD, which have both suffered significant losses.
Investing with a PR% exceeding 200% is not advisable.

Therefore, it is essential to maintain a margin of safety. A PR% greater than 80% is considered too high, and it is not advisable to make the purchase.

As long as the PR% is below 80%, it is fine,
there is no correlation between a lower PR% and being better, or a negative PR% being worse.
Cash flow should not exceed the established limit, regardless of how you manage your cash flow below that limit, it is not better or worse, there is no such thing as the lower the better in cash flow management.

If the company is loss-making, the PR% will be labeled as "LOSS".
A negative PR% means that no new equipment has been added in the last 4 years, and due to depreciation, the value of the machine is decreasing.

Some students asked me: "Does it matter if PR% is negative?"
I replied: "As long as PR% is below 80%, it doesn't matter."
The students asked further: "What about negative PR%?"
I responded: "Is a negative number below 80%?"
The students were stunned and didn't know how to respond.
This course mainly covers basic arithmetic, with few challenging questions.

(©T¸ê4+ªø§ë4-©T¸ê0-ªø§ë0) / (²b§Q4 - ²b§Q0)
A dentist with the surname Li scolded my PR% for being incorrect and demanded that I change it to his own formula: (Fixed Assets 4 + Long-term Investments 4 - Fixed Assets 0 - Long-term Investments 0) / (Net Profit 4 - Net Profit 0).

I instantly recognized that his formula was incorrect. If net profit in year 4 is equal to net profit in year 0, then the denominator would be zero, resulting in infinity. Despite having the same profit in both years, Dentist Li feels that cash flow is a major problem for the company. It's absurd that a company that is still profitable could encounter financial difficulties.

A denominator of zero results in infinity, which is just a basic concept in elementary mathematics. It's astonishing that this person didn't know this and was ranting about it on his blog. He has lost face and yet refuses to acknowledge his mistake. It's been several years, but he still refuses to admit his error and apologize.
Refusing to admit one's mistakes is a sign of a lack of virtue and integrity.

Financial stocks do not apply PR% because they do not have assets such as machinery and equipment. Furthermore, long-term investments in financial stocks tend to be substantial, including loans with a term longer than one year and bonds with a maturity greater than one year. As a result, the calculated PR% can be very high, reaching thousands.

Financial stocks take into account dividend payout ratios above 40%, indicating that a sufficient amount of cash has been paid out. This 40% requirement is derived from two problematic stocks, Yahsin (2418.TW) and SAY, discussed in Lecture 10/21, which will be explained further later.
