Mumbai.Seven of India’s ten most valued companies saw their combined market capitalisation erode by ₹2.05 lakh crore in the past week, reflecting broad-based weakness in equities. Tata Consultancy Services emerged as the biggest laggard, while Reliance Industries also recorded a sharp fall. The losses came amid a wider market slide that dragged benchmark indices lower through the week.

TCS leads losses as heavyweights decline

TCS witnessed the steepest drop, with its valuation shrinking by ₹66,699 crore to ₹8.67 lakh crore. Reliance Industries followed, losing ₹50,670 crore in market value to settle at ₹17.96 lakh crore.

Other major companies that saw erosion in value include:

• LIC
• Bharti Airtel
• ICICI Bank
• Larsen & Toubro

Gains limited to select banking and FMCG stocks

The downturn was not uniform, with a few heavyweights managing to post gains. HDFC Bank added ₹23,090 crore to its valuation, closing at ₹12.08 lakh crore.

Other gainers included:

• Hindustan Unilever
• State Bank of India
• Bajaj Finance

These selective gains offered limited support to an otherwise weak market.

Benchmark indices end week sharply lower

The broader market reflected the pressure on frontline stocks. The BSE Sensex fell 1,830 points, or 2.33 percent, over the week. The Nifty 50 declined 455 points, or 1.87 percent.

On Friday, April 24:

• Sensex dropped 1,000 points (1.29 percent) to close at 76,664
• Nifty fell 275 points (1.14 percent) to end at 23,898

What market capitalisation means for companies

Market capitalisation represents the total value of a company’s outstanding shares. It is calculated by multiplying the total number of shares by the current share price.

For example:

• If a company has 1 crore shares
• And each share is priced at ₹20
• Total market value becomes ₹200 crore

Why valuations rise or fall in markets

Changes in market cap are largely driven by stock price movements, influenced by multiple factors:

• Strong or weak financial performance
• Positive or negative news flow
• Broader economic and market sentiment
• Corporate actions like share issuance or buybacks

Impact on companies and investors

A higher market capitalisation improves a company’s ability to raise funds, secure loans, and pursue expansion. A decline, however, can restrict financial flexibility.

For investors, the impact is direct:

• Rising market cap increases portfolio value
• Falling valuations can lead to losses and trigger selling

For instance, a rise in TCS valuation would boost investor wealth and funding capacity, while a decline has the opposite effect, underlining the sensitivity of market cap to price movements.
