Version 9.11 summary: pages open faster and are easier to read

Published: 2026-11-15

From version 9.11.0 on November 7, 2026 to version 9.11.25, we shipped 26 updates in about a week. Instead of adding new features, we spent this period on everyday usability: pages that open quickly, text that is easy to read, and buttons that are easy to tap.

These improvements change little in how the site looks, so this article shows what got better, and by how much, with measured numbers.

How to read the numbers

  • Scores come from Google's public measurement tool, PageSpeed Insights, and Lighthouse, the engine behind it. Both are out of 100, and higher is better.
  • Smartphone measurements deliberately assume a lower-end device on a slow connection. Scores therefore come out lower than what you actually experience.
  • Scores vary from run to run. We show the range over several runs or the middle value (median), not a single result.

1. Every page starts opening sooner

The time from requesting a page until the server's first response starts arriving has been cut roughly in half.

BeforeAfter
Time until the first response starts arriving0.36–0.42 s0.19 s (median)

This is the time spent communicating with the server only, not including drawing the screen, measured 10 times on each of three main pages.

Because every page shares this wait, you will notice the difference most when you switch between issues one after another, or when you need to check something quickly during trading hours.

2. Issue pages respond right after they open

Scrolling and tapping used to stutter just after an issue page opened. That time is now about one third of what it was.

BeforeAfter
Time the page is slow to respond right after opening (median)about 2.4 sabout 0.75 s
Performance score (smartphone, median of 8 runs)6476

You can scroll to the information you want as soon as the page opens. Content no longer shifts while the page loads, so you won't tap the wrong place because something moved.

3. Pages behind sign-in show their content immediately

My Page, View history, and Watchlists used to show a loading indicator for a while after opening. They now show their content as soon as they open.

PageBeforeAfter
My Page (General Settings)6798
My Page (Notification Settings)6999
View history6591
Issue page (signed in)5880
Watchlist details4573

On the watchlist you open every day, the time until the table of issues appears went from 2.45 seconds to 0.82 seconds. Your morning check, and quick looks during trading hours, take less waiting.

The "Add to Home Screen" and notification prompts also no longer appear the moment a page opens, so you can see what you came for first.

Pages behind sign-in cannot be measured with the public tool. The table shows performance scores measured in our pre-release test environment under smartphone conditions (median of 3 to 5 runs). Of the 27 pages measured, the number scoring below 80 fell from 16 to 8.

4. The top page and the service introduction page are lighter

The amount of data loaded when the top page opens is down by about 40%. Less data means the page opens more easily when you are out or the signal is weak.

BeforeAfter
Program code the top page loads first1,064 KB652 KB (39% less)
Performance score of the service introduction page (Japanese only; smartphone, median of 8 runs)6280.5

The top page's performance score (smartphone) was 55 at version 9.11.2, just after we started. At version 9.11.9 it was 64 to 89 over 8 runs.

5. Text is easier to read and buttons are easier to tap

We checked every page and fixed the places that were hard to read or hard to tap.

  • Faint text (supplementary notes, links, and the red and blue numbers in tables) is now clearly readable, even in bright places and on small screens
  • Links inside sentences are underlined, so you can see at a glance what can be tapped
  • Links that were too small are now easier to tap with a finger
  • With screen reader software or keyboard-only operation, table contents and button destinations are now conveyed properly

The number of runs that scored 100 in Lighthouse's Accessibility check:

ScopeBeforeAfter
93 pages viewable without signing in86 of 182 runs182 of 182 runs
73 pages including those behind sign-in119 of 144 runs144 of 144 runs

The checks cover both desktop and smartphone conditions. This table was measured in our pre-release test environment.

The top page, the service introduction page, and the issue page also now score 100 when the live site is measured with PageSpeed Insights (previously 92 to 96).

6. Other improvements

  • Earnings report summaries are more accurate
  • Fixed dates and times sometimes being displayed incorrectly
  • Fixed pages briefly appearing in the light color scheme right after moving from the service introduction page while using the dark theme
  • Fixed the table scroll position jumping back to the top on the per-issue large short positions page when viewed on a desktop

We will keep improving

Our work on speed and usability does not end here. We will continue with the following.

  • Faster response to your actions: we will shorten the time from pressing a button until the screen changes, based on data from real usage.
  • Checking real-world conditions: the numbers in this article come from measurement tools. We will check whether display times have improved on your actual devices and fix whatever falls short.

If you notice a page that is slow or something that is hard to read, please let us know through "Contact" at the bottom of the page. Day-to-day updates are listed in the Release Notes.
