First, let's look at the first type of effective support level $英偉達 (NVDA.US)$

如今，綠色電已成為市場上的主要力量，其實根源在能源革命，老李之前也說，在碳中和的背景下，綠色電市場可以直到明年，而對於綠色電，我經常與大家分享其投資邏輯。有興趣的朋友可以前往我的主頁查看這些文章。
今天再次提醒您，電力將繼續飆升並以可持續的方式跟踪。
其實，在二級市場做投資，研究是一個方向，做正確的方向，即使一刻追高造成損失也不用擔心，一般趨勢也會推動你前進。走正確的方向，波浪的黃金平移動為戲劇。
$恒生指數 (800000.HK)$恒生指數今天可以維持水衝擊，騰訊真的出現強勢，如果今天騰訊表現稍微弱，估計市場有突破新低點的可能性，從當前市場環境下跌還沒完全結束，需要注意重量和情緒是否有共鳴的可能性，通道下邊的技術水平每日水平才能獲得支撐，在這裡獲得支撐，這裡如果穩定，則開始攻擊向下通道軸，支撐可以看到上一個在 22700 附近的新低點，23500 上壓如果能突破，則將打開新的上行。
個別股票
$騰訊控股 (00700.HK)$騰訊早上強勁攻擊，推動股價再次回到 460 以上，儘管股價回到 460 以上，但需要注意，它還是左邊框衝擊，所以如果明天有反彈可以適當低吸力，不要追上，上壓 500 等待突破。
$比亞迪股份 (01211.HK)$比亞迪今天的表現有點差，周邊新能源行業急劇反彈，特斯拉股價已經回歸 1000 關卡，今天比亞迪只上漲了那麼多，實力顯然無法跟上， $特斯拉 (TSLA.US)$ 
比亞迪短期情況是價值高的短期看跌，只是看看市場這裡就是利用衝擊向下的方式，或者直接隨時的下跌，當前等待調整結束是支柱，以下支撐 240 不跌低於市場將以盒式衝擊方式進行調整。
$小米集團-W (01810.HK)$小米現在趨勢就越多看得越舒服，高點每天越高，技術指標 macd 也開始變紅了，唯一缺點是能量少了一點，能量的量我認為主要或市場整體相對較弱，資本等待看情緒相對強，如果小米出來了不錯的楊線，基金就是瘋狂地抓取芯片。明天如果有機會，我將在小米開張職位，如果明天沒有機會，最晚在聖誕節之後。
$藥明生物 (02269.HK)$昨天無錫生物的位置開盤，今天的振幅顯著減少，有點到節點變化，macd 陰線也在收縮，下一次上升變化的概率將更大，等待趨勢首先修復由看跌引起的陰線。
$京東集團-SW (09618.HK)$

$恒生指數 (800000.HK)$恒生指數輕微震盪，原本良好的趨勢被阿里的突如其來的看跌情緒擊倒，當前市場情緒較為激動，若有情緒回穩，市場將有較大的反彈修復預期。從技術上看，恒生指數的日度水平仍處於下跌趨勢，但若未跌破前低，則無需擔心，下方支撐23000未跌破低位主要吸筹。
個別股票:
$騰訊控股 (00700.HK)$tencent n6006今日回升，小幅回落後，短期僅與指數共振，基本面未有變化，可以放心低吸，但互聯網制造商的情绪需要一些時間來修復，tencent n6006仍然處於交易左侧，或主要以低吸為主，等待突破500以上開啟新的上行空間
$小米集團-W (01810.HK)$小米這個位置基本確定止跌，昨天反包量後，今天有一條低吞噬，現在缺少一個開始信號，如果可以有陽線驅動情緒，小米有潛力成為這個恒生反彈的領軍者。若反彈站穩19元，此波反彈可望見23元左右(等待小米的開倉信號)
$比亞迪股份 (01211.HK)$比亚迪今天再次反弹，但比亚迪的下降趋势已经确认，所以这里可以看作是向下斜率的向下修正的逆转，但新能源板块的估值修复仍在进行中，短期的反弹不适合参与，并且每日水平在240的支撑下将加速下降趋势。
$中信証券 (06030.HK)$中信证券，因为证券公司整体板块争先恐后上下，没有形成券商板块的整体效应，但AH连动明显，并且有可能在配股后修复下跌，可能性转强的可能性很大，如果枢轴支撑19.5是一个上车的好机会。
$藥明生物 (02269.HK)$今天在无锡生物制品开仓了，实际上，从大跌的那天开始，我就开始考虑无锡了，当时的核心观点是存在着很大的交易机会，但必须要有耐心，我选择今天的原因，就是等待第二波纠缠，第一波纠缠之后，有很多投资者以短期游戏心态入场，认为周一的下跌足以把这些短期资金吓出场外，经历了昨日的震荡后，今天选择入场对无锡的资金更有价值，所以我选择了今天入场。
$京東集團-SW (09618.HK)$

今天恒生指數再次跌出股市災難的勢頭，面對的是一碗又一碗，這個市場越來越難玩！


趁著情緒的冷凍點，今天不管買什麼都是一碗麵，通常情緒冷凍點過後會有修復行情，但只是修復，別抱太大希望，數量不能上去，還會有反復震盪。

二级市场是交易的地方，有人的地方就一定会有不同的情绪，今天情绪冷冻点+被迫出逃恐慌盘，明天惯性下跌将是非常好的钓底机会。
短期操作需要坚强的心理素质，大局观，交易系统，技术图形是次要的，控制市场情绪是关键，“情绪”很难量化，但可以理解。
今天的交易正式开始：
$恒生指數 (800000.HK)$恒生指數跌破新低，短期有触底迹象加速下跌，所以位置没有必要恐慌，廉價籌碼也不要丢失，手上叠加周轉的外圍市場也不好，短期股指表現較强，所以現在內容以觀察為主，日期線壓力接近23500水平，如果再次站穩，有可能反彈。
日本股票
$騰訊控股 (00700.HK)$腾讯继续跟随指数下跌，很多人担心腾讯会跌破新低。我只能说概率不大，因为这里的跌与基本面无关，而是情绪的作用，所以下方的空间并不大，不要盲目击杀廉价的股票放手。

$比亞迪股份 (01211.HK)$比亞迪再次下跌，目前估值和業績匹配度不夠，在市場預期修復估值的同時，加上新能源板塊周邊的弱化，出現短期破位的迹象。目前趨勢屬於下跌結構，不適合參與中期反彈，在240處提供支撐。
在概念股崩盤中，我們一定想知道何時適合觀望買入，降幅的核心是阿里，如果它停止下跌，可以大膽觀望買入。 $阿里巴巴-W (09988.HK)$在概念股崩盤中，我們一定想知道何時適合觀望買入，降幅的核心是阿里，如果它停止下跌，可以大膽觀望買入。

Individual stocks:
$比亞迪股份 (01211.HK)$  Jády continued to fall, moving well within expectations, Jády’s head has formed in the short term, and the resonance of the peripheral markets of the new energy vehicle sector fell. There are some differences on the repair of the valuation. On the one hand, profit growth on the other hand, whether the sales of passenger cars will continue to grow, short-term evasion is the main thing. At present, the technical level supports 240. If it falls below, there is the risk of accelerating the adjustment, short-term adjustment waiting for the end of the main.
$藥明康德 (02359.HK)$ Immanuel Kant continued to fall on the negative side, but fell again after the rebound today.

大家好，我是老莉
沒有市場只有上漲不下跌，也沒有市場只有跌倒卻不漲。跳得越高，跌倒的痛苦就越多，蹲得越深，以後跳得越高越遠。
儘管今天的市場再次創下新低，但這一新低可以作為中期市場的起點。因為悲觀主義更徹底地釋放，從交易量的角度來看，市場看起來，在指數處於新低之後，基金看起來就會進入市場。如果市場走出一個巨大的積極明天，這將進一步刺激增量資金的加速進入。
它對市場的短期流動性具有緩解作用。
$恒生指數 (800000.HK)$新低後恆生指數再度回升，短期市場風勢並沒有改變。但是，在市場持續下跌和外部市場的復蘇之後，指數下跌的空間不大，但短期內出現大幅反彈的可能性也不大。是的，等待低位收斂並選擇主要方向。在技術層面上，恒生指數繼續保持在下行通道，日內支撐 23,000，壓力高於 24,300 個等待選定方向。
$比亞迪股份 (01211.HK)$比亞迪完全再現了特斯拉低和高趨勢。值得注意的是，短期內估值過高。其次，雖然行業繁榮不變，但業績的增長率影響估值的調整，而隨著上游價格的上漲擠壓下游利潤，而接近年底，確實存在高低轉換的可能性。目前價格高，等待調整結束。如果盤中支撐 240 突破開向下空間，則向上反彈壓力 280 是向上趨勢線壓力。，等待調整結束。
$中芯國際 (00981.HK)$中芯國際今天繼續下跌，仍然保持著昨天的觀點。這種下降不是由壞消息引起的，情緒下降。Kdj 直接向上分歧，預計將形成一個金叉，以推動股價迎來反卡車。越來越仔細地這個位置成為一個金色的坑。
$中國平安 (02318.HK)$中國平安繼續鞏固可以看出，中國平安最近有明顯的走強跡象，並沒有跟隨指數波動。負面因素用盡之後，有望糾正一年中的下降情況。每日支援主要是 55 次討價還價狩獵，頂部是穩定和 63 開。反彈空間。
$騰訊控股 (00700.HK)$騰訊繼續下行趨勢，短期內再次測試先前低點。目前的股票價格在箱子的底部邊緣仍然波動。但是，可以看出，阿里巴巴的波動性 $阿里巴巴-W (09988.HK)$ ,   $美團-W (03690.HK)$，以及 $小米集團-W (01810.HK)$最近有所下降，基本面已用盡。
中國的概念股現在在左邊，左邊的賠率是足夠的，但穩定和上漲需要時間，並嘗試盡可能低的買入。
