Is Pulz Electronics Limited (NSE:PULZ) a good dividend stock? How can we tell? Dividend paying companies with growing earnings can be highly rewarding in the long term. Unfortunately, it's common for investors to be enticed in by the seemingly attractive yield, and lose money when the company has to cut its dividend payments.

There are a few simple ways to reduce the risks of buying Pulz Electronics for its dividend, and we'll go through these below.

Payout ratios

Dividends are usually paid out of company earnings. If a company is paying more than it earns, then the dividend might become unsustainable - hardly an ideal situation. So we need to form a view on if a company's dividend is sustainable, relative to its net profit after tax. Looking at the data, we can see that 5.5% of Pulz Electronics's profits were paid out as dividends in the last 12 months. With a low payout ratio, it looks like the dividend is comprehensively covered by earnings.

Dividend Volatility

Before buying a stock for its income, we want to see if the dividends have been stable in the past, and if the company has a track record of maintaining its dividend. With a payment history of less than 2 years, we think it's a bit too soon to think about living on the income from its dividend. Its most recent annual dividend was ₹0.50 per share.

Dividend Growth Potential

The other half of the dividend investing equation is evaluating whether earnings per share (EPS) are growing. Over the long term, dividends need to grow at or above the rate of inflation, in order to maintain the recipient's purchasing power. Strong earnings per share (EPS) growth might encourage our interest in the company despite fluctuating dividends, which is why it's great to see Pulz Electronics has grown its earnings per share at 77% per annum over the past five years. The company is only paying out a fraction of its earnings as dividends, and in the past been able to use the retained earnings to grow its profits rapidly - an ideal combination.

We'd also point out that Pulz Electronics issued a meaningful number of new shares in the past year. Trying to grow the dividend when issuing new shares reminds us of the ancient Greek tale of Sisyphus - perpetually pushing a boulder uphill. Companies that consistently issue new shares are often suboptimal from a dividend perspective.
