The daily bhavcopy from the NSE is a goldmine of data. It provides a raw, unfiltered look at the day's market activity. However, many traders, especially those new to the market, make critical mistakes when interpreting this data. These errors can lead to flawed analysis and costly trading decisions. Let's break down the top five mistakes and how you can avoid them.
Mistake #1: Ignoring Corporate Actions
The Mistake
A stock suddenly appears to have dropped 80% overnight. A panicked trader might see this as a massive crash, when in reality, the company announced a 1-for-5 stock split. Calculating returns without adjusting for splits, bonuses, or other corporate actions leads to wildly inaccurate conclusions.
The Solution
Always cross-reference significant price changes with official exchange announcements. A stock's price must be adjusted for these events to calculate true returns. The Daily Market Scan tool flags unusually large price changes and includes a feature to let you manually adjust the previous day's price, instantly recalculating all metrics correctly.
Mistake #2: Confusing Volume with Conviction
The Mistake
Seeing a massive spike in a stock's trading volume and assuming it represents strong buying interest. High volume can also mean high selling pressure or simply a large block deal between two parties with no impact on the open market. Volume alone doesn't tell the whole story.
The Solution
Look at volume in conjunction with the **Delivery Percentage**. A high volume breakout with a high delivery percentage suggests that many traders bought the shares to keep, indicating strong bullish conviction. A high volume with low delivery could just be intraday noise. Our tool calculates both Volume and Delivery Breakouts side-by-side.
Mistake #3: Focusing Only on Top Gainers
The Mistake
Screening for the day's top gainers and assuming they are the strongest stocks. A stock might be the top gainer, but if it's in a sector that performed poorly, it could be an outlier. This is known as "chasing performance" and often leads to buying at the peak.
The Solution
Analyze a stock's performance relative to its peers. Is the entire sector moving up, or just this one stock? A stock that gains 3% in a sector that's down 2% is often stronger than a stock that gains 5% in a sector that's up 6%. The **Sector Overview** and **Relative Strength (RS) Rating** in our tool are designed to show you this context instantly.
Mistake #4: Analyzing Data in Isolation
The Mistake
Looking at a single day's bhavcopy data without any historical context. Was today's volume breakout a one-off event, or is it part of a developing trend? Is the market breadth (Advance/Decline ratio) improving or deteriorating over the last few weeks? A single day is just one data point.
The Solution
Context is everything. Compare today's data with data from the past several days or weeks to identify meaningful trends. The **Historical Analysis** tab in the Daily Market Scan tool automatically saves your daily reports, allowing you to track metrics like A/D ratio and Nifty volume over time on an interactive chart.
Mistake #5: Using Only EQ Series Stocks
The Mistake
Bhavcopy contains data for all series (EQ, BE, T1, etc.). Many traders simply filter for the 'EQ' series, which is correct for most analysis. However, they forget to also filter their Nifty 50 stock list, leading to mismatches and missing data when a stock temporarily moves to another series.
The Solution
Ensure your analysis pipeline is robust. You need to align the 'EQ' series stocks from the bhavcopy with your master list of Nifty 50 symbols. This manual alignment in Excel is tedious and prone to error. Our tool automates this entire process, ensuring a clean, accurate, and perfectly aligned dataset every single time you upload your files.
Stop Making Manual Mistakes
Manual analysis in Excel is slow and prone to errors. The Daily Market Scan tool was built to automate this entire process, giving you clean, accurate insights in seconds.
