Candlestick Chart

Live Update At 11:33:01 EST: On Wednesday, December 31, 2025 Pacific Biosciences of California Inc. stock [NASDAQ: PACB] is trending up by 7.23%! Discover the key drivers behind this movement as well as our expert analysis in the detailed breakdown below.

Quick Financial Overview

Understanding a company’s profits help make sense of numbers. For PacBio, current figures offer a mixed bag. Third-quarter earnings displayed an operating loss of $38.88M, which can cause concern. However, revenue stood firm at $38.44M. While continuing losses worry investors, higher revenue might suggest better growth prospects on the horizon.

Investors have noticed Cathie Wood’s massive PacBio share purchases, pushing the stock price upwards. Stock opened at $1.76, peaked at $1.86, and took some dips to $1.75.

Financially, total assets reached around $803M with solid equity. Despite losses in certain areas, the nagging $380M net loss persists, demanding immediate action to prevent further disappointments. On the bright side, consistent revenue growth might play a critical role next year.

However, warning signs flicker when weighing debt-to-equity ratios. A shallow, quick summation outlines a total debt-to-equity ratio of 19.4%, indicating a bit of strain. The forthcoming J.P. Morgan Healthcare Conference in 2026 will shed light on more initiatives from PacBio, capturing investors’ attention.

The available research on day trading suggests that most active traders lose money. Fees and overtrading are major contributors to these losses.

A 2000 study called “Trading is Hazardous to Your Wealth: The Common Stock Investment Performance of Individual Investors” evaluated 66,465 U.S. households that held stocks from 1991 to 1996. The households that traded most averaged an 11.4% annual return during a period where the overall market gained 17.9%. These lower returns were attributed to overconfidence.

A 2014 paper (revised 2019) titled “Learning Fast or Slow?” analyzed the complete transaction history of the Taiwan Stock Exchange between 1992 and 2006. It looked at the ongoing performance of day traders in this sample, and found that 97% of day traders can expect to lose money from trading, and more than 90% of all day trading volume can be traced to investors who predictably lose money. Additionally, it tied the behavior of gamblers and drivers who get more speeding tickets to overtrading, and cited studies showing that legalized gambling has an inverse effect on trading volume.

A 2019 research study (revised 2020) called “Day Trading for a Living?” observed 19,646 Brazilian futures contract traders who started day trading from 2013 to 2015, and recorded two years of their trading activity. The study authors found that 97% of traders with more than 300 days actively trading lost money, and only 1.1% earned more than the Brazilian minimum wage ($16 USD per day). They hypothesized that the greater returns shown in previous studies did not differentiate between frequent day traders and those who traded rarely, and that more frequent trading activity decreases the chance of profitability.

These studies show the wide variance of the available data on day trading profitability. One thing that seems clear from the research is that most day traders lose money .
