market is a positive response to the release of the new
products. On the day of the plate, the millet group
gained the highest expansion to more than 5% (data)
(Source: Sina Finance). From the user interaction
perspective, Xiaomi has effectively enhanced user
stickiness by organizing activities such as "Mi Fan
Festival" and "Topic Challenge". For example, under
the topic of "MIUI System Upgrade" in 2024, user-
generated content (UGC) accounted for 42%, and this
high proportion of user participation led to a 28%
increase in interaction volume in the same month
compared to , and the share price rose 5.1% in the
same period (source: Weibo Data Center), which is a
strong proof of the role of user-interactive content in
increasing interaction volume and driving the share
price up (source: Sina Finance). This is strong
evidence of the positive role of user interactive
content in boosting engagement and increasing share
price.
In terms of interaction patterns, Xiaomi presents
significant high frequency and strong timeliness. The
average daily release of Xiaomi's microblog account
reaches 3.2 items, and during major events such as the
release of financial reports, the number of releases
will significantly increase to 10 items per day, at the
same time, 60% of the content is released during the
active hours of the users (19:00 - 22:00), which is a
release strategy that ensures that the information
reaches the maximum number of investors and
consumers, and realizes the maximization of the
effect of the dissemination of the information (Data
source: New List Research Institute). In terms of
community stratified operation, Xiaomi divides users
into three categories, namely "core fans", "potential
investors" and "ordinary consumers", and carefully
designs Interactive content. In the "millet
community" forum, technical discussion posts
account for the highest proportion, to meet the core
fans of the pursuit of technical depth; while in the
microblog platform, focusing on emotional narrative,
to attract a wider range of user groups. Through this
community layered operation strategy, Xiaomi can
effectively enhance brand loyalty.
Key events of different natures have had very
different impacts on Xiaomi's stock price. Positive
events such as new product releases and earnings
announcements tend to push the stock price up in the
short term. 2024 SU7 car release, the launch of the
conference's network sound volume of more than
110,000, the number of interactions of more than
346,000 people, the spread of the heat index of
85.38% (data source: Qingbo big data). Xiaomi
Group (ADR) rose over 12% at one point that night,
and the share price of Xiaomi Group in Hong Kong
stocks on April 2 opened sharply higher by about
15%, once as high as HK$17.34, and closed 8.97%
(data source: Yahoo Finance). And public opinion
crisis and other negative events may lead to stock
price overshooting, February 27 " Lei Jun's wealth
exceeds Zhong Glittering " topic on the top of the hot
search list, microblogging interactions instantly
increased by 320%, but one hour after the rumor was
disproved, retail investors panic selling, resulting in
stock price amplitude of 12%, market value
evaporated more than 80 billion Hong Kong dollars
(data source: Bloomberg). (Source: Bloomberg). This
incident highlights the "asymmetric effect" of social
media's emotional contagion, where the pulling
strength of positive interactions on stock prices is
much lower than the suppressive effect of negative
public opinion.
