**Progress**(Nasdaq:PRGS) has soared 10.1% to reach a current price of $21.10 per share. So far today, the company's volume is 908,609 shares, three times the average daily volume. If a stock price makes a big move up or down, volume lets us know the significance of that move. Investment valuation ratios can be very useful in determining the value of a stock, but it is very important to keep in mind that while some financial ratios have general rules (or a broad application), in most instances it is a prudent practice to look at a company's historical performance and use peer company/industry comparisons to put any given company's ratio in perspective. The price/book value ratio, often expressed simply as "price-to-book", provides investors a way to compare the market value, or what they are paying for each share, to a conservative measure of the value of the firm. PRGS' P/B ratio of 2.03 shows that its share price is higher than its book value. This implies that investors expect management to create more value from a given set of assets and/or that the market value of the firm's assets is significantly higher than their accounting value. All else being equal, a stock with a low P/B value ratio is more attractive than a stock with a high ratio. SEE: Investment Valuation Ratios: Price/Book Value Ratio

**Cepheid**(Nasdaq:CPHD) has fallen 8% and is currently trading at $36.01 per share. So far today, the company's volume is 1.3 million shares. In technical analysis, trading volume is used to determine the strength of a market indicator. Investment valuation ratios can be very useful in estimating whether a stock price is too high, reasonable or a bargain investment opportunity. The debt ratio gives users a quick measure of the amount of debt that the company has on its balance sheets compared to its assets. CPHD has a debt ratio of 22.6%, which is fairly low. In other words, the company is less sensitive to changes in business or interest rates since less of its cash flow is dedicated to paying off loan expenses. However, one thing to note with this ratio: it isn't a pure measure of a company's debt (or indebtedness), as it also includes operational liabilities, such as accounts payable and taxes payable.

Slipping 7.2%,

**Ubiquiti Networks**(Nasdaq:UBNT) is currently trading at $11.02 per share. At 231,054 shares, the company's volume so far today is 0.7 times the average volume over the last three months. High volume indicates a lot of investor interest while low volume indicates the opposite. Valuation ratios allow the investor to make a quick determination as to a company's investment value. While measuring a price/earnings ratio (P/E ratio) is a popular valuation technique, the measure cannot be calculated for companies without earnings, so some investors analyze the price/sales ratio. The P/S ratio for UBNT is a high 3.7. In young companies, a high P/S ratio is a sign of sales growth that is expected to turn into earnings and cash flow. All things being equal, a low P/S ratio is good news for investors, while a very high one can be a warning sign.

**ImmunoGen**(Nasdaq:IMGN) has slipped 4.6%. The company is trading at a volume of 509,923 shares. If a stock is trading on low volume, then there is not much interest in the stock. On the other hand, if a stock is trading on high volume, then there is a lot of interest in the stock. Investors can make use of valuation ratios to estimate whether a stock is fairly valued. The price/book value ratio is one of the more common methods of determining whether a stock is fairly valued. IMGN has a P/B ratio of 15.07 which shows that its share price is higher than its book value. This may be a sign that the company is overvalued. One problem with the P/B value ratio is that it can be difficult to calculate the true book value of a company, so investors should be aware that many measures of book value may provide only a rough estimate, and should be taken with a grain of salt.

After rising 3.9%,

**Medivation**(Nasdaq:MDVN) is currently trading at a share price of $55.50. The company's volume is currently 589,447 shares for the day, 0.7 times the current daily average. A stock's volume conveys how excited investors are about it. Looking at a company's valuation ratios is a good way of getting a basic idea as to its value as an investment. The debt ratio measures the leverage of a company, and a company's leverage is a good way to assess risk. MDVN has a high debt ratio of 79%. As such, the company is highly leveraged and not highly liquid. As with all financial ratios, a company's debt ratio should be compared with the industry average or similar companies.

**OYO**(Nasdaq:OYOG) has moved up 3.3% and is currently trading at $118.80 per share. The company's volume for the day so far is 6,554 shares. Volume is used to evaluate how meaningful the price movement of a stock is. Investors can use valuation ratios as tools to estimate what kind of deal a particular investment is. The price/sales ratio measures a company's stock market value by its total revenues or alternatively, a company's price per share by its revenue per share. OYOG's P/S ratio of 3.06 is on the high side. This could be a good sign if the share price increases. It is important to keep in mind when looking at the P/S ratio that just because a company is generating revenues, this does not mean that the company is profitable, and in the long run, profits drive stock prices.

After a decline of 3.1%,

**IBERIABANK**(Nasdaq:IBKC) has hit a share price of $45.54. The company's volume for the day so far is 116,129 shares, 0.8 times the current three-month average. Price change alone is not enough to know how a stock is doing. Volume is an important secondary indicator used to confirm trends suggested by price movement. Valuation ratios include the price to earnings (P/E) ratio, the price to earnings growth (PEG) ratio, the price to sales (P/S) ratio, the price to book (P/B) ratio, and the dividend yield. The capitalization ratio is calculated by dividing long-term debt by the sum of long-term debt and shareholders' equity. IBKC has a fairly low capitalization ratio of 17%. A very low capitalization ratio might be a sign that the company is stagnating and reducing the potential earnings for shareholders. A low level of debt and a healthy proportion of equity in a company's capital structure is an indication of financial fitness.

**The Bottom Line**The nature of the market is such that stocks will have good days and bad days. Paying close attention to the previous ratios will help you identify key times to adjust your strategy. Keep in mind that all these ratios should be compared against historical numbers and industry information in order to get a more complete picture.
